- Application filed April 2, 1906. Serial No. 309,378-

To all whom 'it may concern:

Be it known that I, CANFIELD J osnrn' Rousseau, a subject of the King of Great Britain, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Rotary Explosion-Engine of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved rotary explosion engine which is simple and durable in construction, very effective in operation, and arranged to give a plurality of impulses to the rotator on every revolution thereof. a

The inventioh'. consists of novel features and parts and combinations of the same which will be more fully described hereinafter and then pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in both the views.

Figure 1 is a sectional side elevation of the improved engine, and Fig. 2 is a transverse section of the same onthe line 22 of Fig. 1.

The cylinders A A of the engine are provided with intersecting bores A, A in which are mountedto rotate a rotator B and an abutment C respectively. The

rotator B is secured on a main shaft D journaled in suitable bearings ananged in the cylinder heads, and on the outer end of the shaft D is fastened a pulley D or a similar device for transmitting the rotary motion of the engine to other machinery. 0n the shaft D butside of the cylinder A is also secured a gear wheel E in mesh with a gear wheel E secured on the outer end of a shaft F on which the abutment Cis fastened, and which shaft F is journaled'in the heads of the cylinder A, The rotator B is provided with radially disposed sliding piston heads B each mounted on a screw rod G and pressed on by a spring H to normally hold the piston head in an outermost position so that the outer end of the piston head is in contact with the inner peripheral surface of the bore A. The abutment C is provided with a plurality of compression chambers C g each having a fiaring'mouth 0 leading to the peripheral face of the abutment C, as plainly illustrated in Fig. 1, and the said chambers C and their mouths (l are arranged to register with the piston heads B when the engine is running. Each of the chambers C is adapted to register with igniting devices I and I held in recesses A formed on the inside of one of the cylinder heads, as plainly shown in Fig. 2, so that when the engine is running and one of the chambers C registers with the recess A containing the igniting device 1 or I in active position, then an ignition of the compressed charge contained in thechamber C takes place .to act on the piston head B in register at a time with this chamber, to rotate the rotator B either in the direction of the arrow aor in the inverse direction thereof, according to which of the igniting devices I or I is in active use at the time.

As shown in Fig. 2 the igniting device is in the form of an electric plug, controlled in the usual manner by a suitable controlling device .1 from the main shaft D of the the engine, so that the charge is ignited at a proper time by either of the igniting devices I, I.

The bore A is connected with'pipes K and K,

either of which may be the admissionpipe and the other the exhaust pipe: for instance, as shown in Fig. 1, the pipe K is the admission pipe for admitting the explosive mixture to the bore A, while the pipe K is,

for the time being, the exhaust pipe; but it is evident that by suitable valve connections the pipe K may be made the inlet pipe for the explosive mixture, while the pipe K then becomes the exhaust pipe.

The operation is as follows: The explosive mixture, passing by the pipe'K into the bore A, is carried by the advancing piston head B along in the bore and into and through the mouth G into the chamber 0, then moving into register with the bore Thus, as the piston head B advances to finally pass into the mouth C of this registering chamber 0, it is evident that the charge'is compressed and confined within the chamber 0, and, as the piston head B now moves past its vertical center together with the filled chamber 0 into the position shown in Fig. 1, it is evident that when an explosion now takes place the force exerted against this piston head B rotates the lrotator Bin the direction of the arrow a. In the meantime, the next following piston head B carries a charge along to force this charge into the next following chamber 0 to compress and to confine it therein, the compressed charge being finally ignited by the igniting device I immediately after this piston and the filled chamber 0 in register with this piston have passed the vertical position, so

ings, and corresponding chambers C, it is evident that three successive impulses are given to the rotator B by each revolution thereof, and, consequently, a continuous and steady rotary motion is given to the shaft D and the machinery connected therewith. When it is desired to reverse the engine the igniting device I is cut out and the igniting device I is cut in, and the explosive charge is admitted to the bore A by way of the pipe K while the exhaust takes place by way of the pipe K. In this case the charge admitted into the bore A is carried along by the advancing piston head and forced into the corresponding chamber-C to be compressed therein and finally exploded by the igniting device J after the piston has passed a vertical position to the right hand side, so that the rotator B is rotated in the inverse direction of the arrow a. Each mouth .0 is shaped to, open into the bore A shortly after the advancing piston head B has passed the inlet pipe K or K, so that the compression of the charge is gradual by the advancing piston head, which latter closes the mouth 0 of the filled chamber whil'e'passing from the vertical position to the igniting position. It is understood that after the pistonhas received an impulse and passed the exhaust pipe K or K, then exhausttakes place 'through this pipe and any residue of burned gases left in the chamber O is passed to the atmosphere through a suitable exhaust port L or L formed in the wall of the boreA From the foregoing it will be seen that the engine is very simple and durable in construction, is composed of comparatively few parts, not liable to get easily out of order, and the engine can be readilyreversed.

It is understood that I do not, limit myself to the number ofpiston heads B and chambers C employed, as the same may be varied without deviating from the spirit of my invention, I

Having thus described my invention, I claim as new and desire to secure by Letters Patent:
